STEM WINDING AND SETTING MECHANISM FOR CLOCKS AND REGULATORS.

SEECIPICATION forming part of Letters Patent No. 342,415, dated May 25, 1886.

Application filed November 17, 1885. Serial No. 183,129. (No model.)

To all whom it may concern:

Be it known that I, J OHN ZELLY, a subject of the Emperor of Germany, residing at Oincinnati, Hamilton county, State of Ohio, have invented a new and useful Separate Stem- \Vinding Clock, of which the following is a specification.

My invention relates to such clocks and regulators as are driven by one or more springs; and the object of it is to provide a simple, durable, and easy winding and setting mechanism, which winds either spring separately, and also sets the hands, dispenses with key-holes in the dial-plate, removal or turning or of the clock, and opening of the glass front, and makes it consequently more dust-proof. It also guards against any possible damages to the clock mechanism arising from turning the wrong way, as my device is operative, no matter which way the handle may be turned. I attain these objects by the construction illustrated in the accompanying drawings, in whieh Figure 1 is a rear view of a clock, partially in section, and the back of the clock-case be ing removed. Fig. 2showsin asectional View the other position of the winding handle or knob and its accessory parts. Fig. 3 shows in a similar View to Fig. 1 a modified form of my invention.

Each of the mainspringarbors a a carries on one of its ends loose gearwhecls b 1/. Big idly connected to one of them (in this case wheel 1)) is a bevel-wl1eel, c, which derives motion from another bevel-wheel, (Z, on shaft 6. "Shaft c rests and revolves in two bearings, A A, extending from the clock-movement frame A. The square portion 0 of shaft 6 fits into a corresponding recess, 0, in stem 0 of sliding handle or knob 0. Beyond the square portion 0 the shaft becomes round again at c. This round end 6 slides in the continuation c of recess 0 in stem C. Stem 0 extends through the clock-case,and has connected to its external termination a suitable knob or handle, 0. That portion of handle 0 which is nearest to the clock-case is tapering inwardly, and fits in a corresponding recess or socket, 7, in the clock-case. By this arrangement a close and tight joint is secured. The winding of the springs is done in the following manner: Turning knob O to the right,

lVheel (Z turns wheel 0 in the direction of the arrow. \Vheel b,being rigidly connected or in one piece therewith, turns in the same direc tion. XV heel I), being in gear with wheel I), and following it in the direction of the arrow, carries a pawl, f, kept from displacement by spring 9, which engages with ratchet-wheel 71 compellingitto rotate. This ratchet-wheel sits on the square termination of the springarbor, a, to which one end of the corresponding spring is connected, and as the arbor turns with the ratchet-wheel the winding of the respective spring is accomplished. \Vhile this is going on, pawl f, with spring 9, sitting on wheel I), recedes from the ratchetavheelh, which sits on the square termination of the other spring-arbor, a, leaving these parts undisturbed.

In turning knob C to the left all wheels revolve in opposite direction, as explained above and indicated by arrows. engages with ratchet-wheel h, which turns spring-arbor a and winds the corresponding spring. Pawl f recedes, now, from the ratchetwheel h, which remains stationary. Those ratchet-wheels commonly used in all clocks (not shown in the drawings) may be placed at the other ends of the spring-arbors or at the same ends between the clock-movement frame and the wheels b Z).

That portion of my invention appertaining to the setting of the hands is constructed and operated in the following manner: The center shaft or hand-arbour,extends far enough back and out of the clock-movement frame A, so that crown-wheelj may clear sufficient] y any other parts ofthe winding device. This crownwheel follows the motion imparted to it by pinion 7; on shaft It, which revolves in the upper portion of bearings A A. That end of shaft 7; next to the knob 0 extends beyond its bearing, and carries a pinion, it. By pulling knob C out of its socket, wheel on, sitting on stem 0, will engage with pinion 70', (see Fig. 2,) and by turning knob G to the right or left while in this position the hands may be turned in either direction. Vheel mturns pinion L, and pinion it, sitting on same shaft with pinion 7;, turns the crown-wheelj, which sits on the hand-arbor. As crown-wheelj and lawl f 7 ICO pinions 7c and k,are always following the n10- tion of the hands, it is necessary that handle- 0 should always be pushed in after the setting of the hands, so as to disengage wheel at from pinion It".

To guard against forgetfulness of the operat01',a spiral spring, a, bearing against flange 0 on stem 0, may be inserted, which pulls handle O,with stem 0 and wheel m,back into its socket as soon as the handle is released. That round end portion, 6, of shaft 0, which in all positions of handle 0 remains in its recess cin stem 0, acts asacentral guide against displacement, and insures a secure engagement of the square portion 6 into its recess 0. For symmetrical and ornamental reasons anotherknob, S, may be placed on the other side, but is without any function.

Fig. 3 shows a clock with very large springbarrels, as where the springs are some distance apart. In such a case the wheels I) I) would have to be very large. To overcome this I substitute (without changing the spirit of my invention or adding another one) an additional wheel, d, with like functions as wheel d. In turning the winding-handle to the'right or left the same actions will take place, and one or the other spring 'will be wound in the same manner as already described, ratchet wheels, handle, and setting device all remaining the same.

Many other modifications might be substituted without constituting a new invention.

Shaft 6 may be Vertical or in any other suitable place to conform to the style of the clock case. Neither do I confine myself to the kind of gear wheels used they may be tooth, crown, or bevel wheels-nor to any particular kind of ratchet device.

Having thus described my invention, what I claim, and want to secure by Letters Patent, is as follows:

1. In a stem-winding clock, the adjustable handle 0, with stem 0, recessed at c c, and

shaft 6, carrying wheel (1, portions 6 e of shaft 6 fitting into said recesses c c, and portion 6 acting as central guide to stem 0 of knob O.

2. In a stem-winding clock, the winding device consisting in the combination of handle 0, recessed stem 0, and shaft 0, carrying wheel (I, with winding-wheels-c b b, sitting loose on their respective spring-arbors, having springs and pawls g f g f, and ratchet-wheels h h being fast with their respective spring-arbors. 3. In a stem-winding clock, handle 0, with stem 0, being recessed and receiving the end portions of shaft 0, as above described, and shaft c,carrying wheels (I d, which are in gear with winding-wheels b b, sitting loosely on their respective spring-arbors, having springs and pawls gfgf, which, as handle 0 is turned either one or the other way, act alternately and separately on their corresponding ratchet-wheels, h h, being fast with their respective spring'arbors.

4. In astem-winding clock, the handsetting device consisting of adjustable handle 0, stem G, carrying wheel in, the whole sliding on and being guided by a portion, 0-, of shaft 0, and held in its normal position by spring a, bearing against flange 0, and pinion it, into which wheel at engages when handle 0 is pulled outwardly, and which sits 011 shaft k, on which sits another pinion, k, which imparts motion to crown-wheelj on hand-arbor 5. In astem-winding clock, the combination of handle 0, recessed stem C, shaft 6, with wheels (I, winding-wheels b c b, and ratchetwheels J1, h, with wheel m, pinions 76 k on shaft 74, journaled in bearings A A, and crown-wheelj.

In testimony of which invention I hereunto set my hand.
